What is typically the first step in preparing to make a new denture for a patient with tori?

The initial step in preparing to make a new denture for a patient with tori involves addressing the anatomical features present in their mouth, specifically by removing the tori. Tori are bony growths in the mouth that can interfere with the fitting and comfort of a denture. By removing these growths, you create a more favorable tissue contour that facilitates an optimal fit for the new denture. This step is critical for the successful design and function of the prosthetic, as it helps prevent potential discomfort and issues such as sore spots caused by the denture resting on the tori.

Addressing the other options: adjusting the current denture may not be effective if the underlying issues are related to anatomical structures. Thorough cleaning, while important for maintaining oral health, does not address the need for procedural changes inherent to the new denture-making process. Taking impressions is typically a follow-up step that comes after managing any anatomical challenges for ensuring the denture fits correctly.
